THOUSAND OAKS, Calif., March 18, 2011 /PRNewswire/ -- Amgen (Nasdaq: AMGN) today issued the following statement:
Amgen has received notice that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a negative opinion for Amgen's application to extend the marketing authorization in Europe for Vectibix® (panitumumab) to include combination with chemotherapy for the treatment of patients with wild-type KRAS metastatic colorectal cancer (mCRC).

Amgen remains committed to patients with this aggressive disease, for whom there are limited treatment options.

Furthermore, use of Vectibix is not recommended in patients whose tumors have KRAS mutations in codon 12 or 13. In Japan and Israel, Vectibix is approved for use in combination with chemotherapy for patients with wild-type KRAS mCRC.
